TOPIC: CHEMICAL BONDING: Ionic, Covalent, Metallic
Generally, to understand and explain why atoms combine with one another to form the vast array of chemical substances that exist. Specifically, to become familiar with ionic, covalent and metallic bonding and with network and molecular materials.
OBJECTIVES: You have completed this lesson when you can:
1. Given any collection of atoms determine what type of bonding will hold them together.
2. Given any collection of atoms determine whether they will bond together as molecules or networks.
3. Given any collection of atoms determine whether they will bond together as an element, an alloy or a compound.
4. Explain what happens to the electrons of individual, isolated atoms when they come in contact with and fall under the influence of other atoms.
5. Describe the nature of ionic bonding and explain why it results in the formation of networks and compounds, but not elements and not molecules.
6. Use the periodic table, our current atomic model and the octet rule to determine the charges (oxidation states) of ions formed by the representative metals and nonmetals.
7. Use lists to determine the charges (oxidation states) for the ions of multivalent metals.
8. Use the charges of cations and anions to determine the formulas of ionic compounds.
9. Describe the basic model of covalent bonding. Also, describe and identify the variations that occur in covalent bonding with respect to numbers of electrons (multiple bonds), origin of electrons (coordinate covalent bonds), and polarization of bonds.
10. Explain how covalent bonding can result in both network and molecular materials, in both elements and compounds, and in polyatomic ions.
11. Use our current atomic model, the periodic table, the octet rule, and Lewis diagrams to depict, predict and explain the covalent bonding patterns in many of the covalent molecules, networks, elements and compounds that exist.
12. Describe the nature of free radicals and relate their degree of reactivity to the arrangement of their electrons.
13. Define and describe electronegativity. Relate its magnitude to the position of an element on the periodic table. Describe its application.
14. Describe the nature of metallic bonding. Relate it to the observed properties of metals, our current model of atoms and to the position of elements on the periodic table.
15. Explain how metallic bonding results in networks and why it is associated with elements and alloys but not compounds.
16. Describe how ionic, covalent and metallic bonding are different from one another and in what ways they are similar to or blend into one another.
